Kennametal 4109663 Grooving Insert NG2031 KCU25 Carbide

Product Description

The KENNAMETAL 4109663 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Built to the Top Notch series standard, this right-hand insert carries the KCU25 manufacturer grade and features a physical vapor deposition (PVD)-applied AlTiN coating for extended tool life in abrasive and interrupted-cut conditions. The cutting width measures 0.79 mm (0.0311 inch) with a maximum depth of cut of 1.27 mm (0.0500 inch). The corner radius is 0.09 mm (0.0035 inch), and the included angle is 55 degrees. This insert uses a clamp-style holding method and is suited for machinists and tooling specialists working to tight groove tolerances in production environments.

This insert is intended for use on CNC turning centers and manual lathes where narrow, precise grooves are required. The NG insert style and Top Notch series designation match the corresponding KENNAMETAL Top Notch toolholders designed for this insert family. The metric sizing (Insert Size 2031) and right-hand orientation make it appropriate for standard OD grooving applications in production and job-shop settings. Material grade classification is C2 and C6, covering a broad range of workpiece materials including steel, cast iron, and non-ferrous alloys.

Installation Notes

Installation is performed by a machinist or tooling technician following the machine tool manufacturer lockout/tagout procedures before changing inserts. Seat the insert fully into the toolholder pocket and torque the clamp screw per the toolholder manufacturer specification. Inspect the insert seat and clamp for debris or damage before seating a new insert. Do not operate the insert beyond its rated maximum depth of cut.
